Electric Control System Analysis And Design Of Linhuan Coal Mine's Elevator

The mine elevator is named as the throat of mine, and it is the most vital equipment in mine. The elevator change along with distance and energy, and the characteristic of electric drive is very complex. The electrometer move frequently positive and negative, and always run pass load, and electromotion and apply the brake transform continually. The developed electric control system of mine hoist will greatly promote productive efficiency and working safety. In recent years, with the development of our national economy and need for mineral resources, the technical requirements for productive activities of mine were being higher and higher.At present, Linhuan Coal Mine with adjusting speed of AC series resistance and the Simulating Electronic control system. Now we are facing a problem of technology reform on a large scale at electric control system of mine hoist. The controller of mine elevator come forth new visage, the level of automatization and safety and security arrived at the new altitude, and provided a new and modern manage and monitor means in the design of controls system of mine elevator. The system is credible, the precision of control is high, and can fulfill the requirement of the local manufacturing.
